What is answer garreet needs it pls "Caprice adds equations A and B to solve this system of equations. What makes this approach a valid method in general for solving a system of equations?"

answer: h

step-by-step explanation:

a is the correct

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
